我已经在新的iMac(运行Big Sur)上按照说明(来自https://docs.nativescript.org/environment-setup.html#macos-ios)重新安装了native - script。
昨天安装后工作正常，但今天我无法在ios模拟器(或Android虚拟设备)中运行应用程序。
ns doctor在终端中的命令初始显示如下:
No issues were detected.
✔ Your ANDROID_HOME environment variable is set and points to correct directory.
✔ Your adb from the Android SDK is correctly installed.
✔ The Android SDK is installed.
✔ A compatible Android SDK for compilation is found.
✔ Javac is installed and is configured properly.
✔ The Java Development Kit (JDK) is installed and is configured properly.
✔ Xcode is installed and is configured properly.
✔ xcodeproj is installed and is configured properly.
✔ CocoaPods are installed.
✔ CocoaPods update is not required.
✔ CocoaPods are configured properly.
✔ Your current CocoaPods version is newer than 1.0.0.
✔ Python installed and configured correctly.
✔ The Python 'six' package is found.
✔ Xcode version 12.5.1 satisfies minimum required version 10.
✔ Getting NativeScript components versions information...
✔ Component nativescript has 8.0.2 version and is up to date.
当我尝试在Android上运行它时，同样的事情也发生了。
尝试在ios和Android上同时运行后，ns doctor添加以下行:
✔ Component @nativescript/core has 8.0.8 version and is up to date.
✔ Component @nativescript/ios has 8.0.0 version and is up to date.
✔ Component @nativescript/android has 8.0.0 version and is up to date.
所以平台似乎被适当地添加了。
任何帮助都将非常感激!

感谢你的报告，我们已经确认了最新webpack版本中的一个重大变化:https://github.com/webpack/webpack/releases/tag/v5.51.1
你可以切换你的包。现在使用rc来解决这个问题，如下所示:
"devDependencies": {
...
"@nativescript/webpack": "rc"
},
然后ns clean，你应该可以运行你的应用程序了。
我们还发布了另一个beta标签，将webpack固定在5.50.0上，这样做ns clean而不需要在您自己的包中进行任何其他依赖更改。Json现在也可以工作了。
